IMPROVEMENT IN WAGON-BRAKE.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, SAMUEL E. HYNDMAN, of Middletown, in Butler county,in the State of Ohio, have invented a new and useful Improvement inW'agon-Brakes; and I do hereby declare that the following is a full andexact description thereof, reference being bad to the accompanyingdrawings, and to the letters of reference marked thereon.

Figure 1 represents a top view of my invention as applied to a wagon.

Figure 2 is a vertical sectional view, taken at the line z x of fig. 1.

In the accompanying drawings, a indicates the axle-tree; b, thesand-board; c c and g g, the hounds; d d, the hound-braces or sliders;h, the tongue-bolt; and z, the wagon-tongue.

My improved brake consists in the arrangement of two brak e-levers ff,secured to the hounds c c by the rear right-angular portion of thebraces d d, which .pass through the'brake-levers ff and hounds c c at 0,and of rods e e, connecting the rcar portion of the tongue-hounds g gwith the inner ends of the brake-levers The tongue-bolt h, whichconnects the tongue-hounds g g with the bounds c c, has its endsextending through the hounds gg, resting in slots 'r 1', made in thehounds c c, the purpose of which will be herein explained. The rear endsof rods 6 e, connecting with the brakes ff, may be secured thereto bynuts and screws. The metal strap or plate 17, fastened to the hounds ce, is provided with a bolt hole, through which the bolt s will freelypass, and enter into ahole in the rear end of the wagon-tongue. Thisbolt 8 (for the o'rdinary general use of the wagon) may hang suspendedfrom a cord; but when it is desired to back the wagon withoutbringingthe brakes into action the bolt 8 will be dropped in place.

The operation of my improved brake I will now describe. As the wagonprogresses on ordinarily level ground, or when ascending an inclination,the brakes will be kept out of contact with the wheels by the action ofdrawing the load by the tongue, the double-trees being fastened theretoat the hole it; but when the wagon is descending an inclination the actof holding back by the team will cause the tongue, with the hounds ggand bolt 7:, to slide backwards, (the bolt it working freely with itsends in the slots 1' r,) thereby thrusting the rods e e, which connectwith the inner ends of the brakes, and causing the brakes to move aroundon the bolts, (consisting of the bent end of sliding-iron or brace 61,)which secure them to the hounds c 0, thus bringing the short ends oflevers ff in contact with the perimeter of the'wheels A A. As soon,however, as the wagon again reaches the level ground the action of theteam to draw the load will disengage the brake-levers with the wheels bysliding the tongue, with its hounds and bolt it, forward, the boltresting against the forward ends of slots 'r 1' in the wagon-hounds a c.The act of the team in holding back from the end of the wagon-tongue, inthe usual manner, will effectually bring the brakes into action; andthe'reta-rding power which they will exert will depend upon the width ofthe hounds between the wheels, because the fulcra of the levers ff, whenbrought near the wheels, will afford greater leverage, and diminish thepower exerted by the team in holding back the load when descending aninclination. My invention is adapted to he used on wagons of ordinaryconstruction, and involves very slight mechanical changes therein, theslots in the bounds for the bolt by which the wagon is drawn, the rods ee, and brakc-leversff constituting the essential features of myimprovement. The cheapness and simplicity of the structure I deem to bea very important consideration. The bolt it, as before remarked, isintended to be inserted when it is desired to prevent the brakes frombeing brought into action, and therefore may be termed the lockor-break-lock bolt.

I am aware that wagon-brakes operated by the team have been constructed;but I do not claim such a principle of operation irrespective of themode of construction and arrangement.

Having fully described the construction and manner of using my improvedwagon-brake, what I claim, and desire to secure by Letters Patent, is-

The brake-levers rods e e, in combination with the slider-braces d ol,hounds c c, and tongue 2', sliding-bolt h, and lock holt s, when theparts are constructed, arranged, and operate in the manner and for thepurpose specified.

Witness my band this 28th day of January, 1867.
